[Stereotactic radiosurgery of brain tumors]

Stereotactic radiosurgery is today a well-established treatment modality for various intracranial pathologies. The principle of high dose focused intracranial radiation guided by stereotactic technique ("Gamma Knife") was introduced by the Swedish neurosurgeon Prof. Lars Leksell in 1968. After the advent of CT and later MR imaging, stereotactic radiosurgery evolved rapidly regarding indications, and new technical solutions made it possible for linear accelerator systems to perform radiosurgery. A huge number of patients are treated yearly worldwide with this technology. In this article we overview the major indications, advantages and possible complications of stereotactic radiosurgery.
